To all whom it may concern Be it known that I, JACOB H. Wnrsenoo,residing at St. Louis, Missouri, and being a citizen of the UnitedStates, have invented certain new and useful Improvements in Cast-SteelBodyBolsters; of which the fol lowing 1s a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preview. Eig. etis an endelevational view of the cast" metal parts of the bolster comprising thepresentinvention. Fig. 5 is a section'al" view, the section being takenOn line.

5''5 of Fig. 2, looking inthe direction indicatedby the arrow. Fig. 6 isa similar view, the section being taken on line 6-6 of Fig. 2, lookinginthe direction indicated by the arrow.

Referring to the parts, it will be noted that the major portion of thebolster, forming the subject-matter of the application, is of castmetal, comprising a central filled portion 7 and wings 8-8, with acontinuous bottom flange 9 extending from end to end of the bolster andwith sill pockets 10 interosed between the wings 8 and the centralfiller portion 7. Extending longitudinally of the car underframe, whenthe bolster is in position, and transversely of the bolster are verticalflanges 12, to which are attached the lower portions'of the Webs 13 ofcenter sills, which center sills will be hereinafter more specificallydescribed. Opposite the flanges 12 and comprising a, part of the flangeoutlining the wings 8, are other vertical flanges 14;, which, with thebottom flange 9, outline. said sill pockets, which pockets are open atthe top for the insertion therein of center sills of a car underframe.Spanning the sill pockets 10 and lapping the bolster Wings 8 is a topcover plate 15, which is secured by vertical rivets 16 to l iSpecification of Letters Patent; Application filed December 9, 1913.Serial'No. 805,558.

flanges 17 of said wings," said top cover plate 15 having a thickenedportion 18, :which provides shoulder-s19 adapted to con- ;tact with theupper inner faces of said vertical walls 14, so that when a car in whichthe bolster is employed is lifted by means of fjacks placed. under theouter ends of said bolsters and the upper portion of the bolster :is incompression, said shoulders 19 will be incontact with said upper innerfaces of the vertical walls 14, thereby relieving the rivets 16- ofstresses ordinarily incident to such operation. To compensate for theincreased weight due to the thickened portion 18 of v :the cover plate,channels-20 are formed in the upper face thereof, said channelspreferably extending at each side past the central filler. a

In assembling the parts shown, the sills having been first provided withslots therefor, the top cover plate 15 is projected; through said slots21 of the-sills, said slots being preferably only suiliciently large topermit ready insertion of said top cover late, after which the remainingportion of t e bolster, including the Wings 8 and central filler, islifted to position in contact with the underside of said top coverplate, and connected thereto and to said center sills. onnected with thewebs 13 of the center'- sills are top and bot-v tom rolled sections 25and 26, formin compression and tension chords for sai sills,

the center sills intermediate theflanges 25' the parts are assembled ashown in Fig.1,

increase the sectional area of the sills. at the bolster and occupy aposition below the middle portion of said cover plate 15. The shoulders19 of said cover plate depend be- .low the normal plane of the topmiddleportion of the body. of the bolster into the pockets 10, and thecover plate 15 will be supported by the wings 8 and central filler ofthe bolster. The bolster filler portion 7 is of less height than thebody portion of the bolster wings. or extensions adjacent said pockets10, hence the thickened or inset depending portion ofthe plate 15 withits shoulders 19 rest in horizontal alinement with the inner or middleportions of the top bolster flanges 17, that is in alinement with thebody portions of the wings, thereby pro- Bum vertical inner faces ofsome of said walls.

2 In a cast bolster, a unitary casting.

comprising a center filler portion, extensions or wings projectingoutwardly at each side of and to a greater altitude than said portion,said bolster having sill pockets at two sides of said filler portion, atop cover plate riveted to said extensions and depending shouldersformed on said cover plate adapted to contact with inner faces of someof the walls of said pockets.

3. In a bolster, a center filler portion having vertical walls, centersills riveted directly to said walls and extending to a plane higherthan said walls, said bolster having wings extending transversely ofsaid sills and to a plane higher than said centerfiller and having sillpockets intermediate said wings and center filler portion, and a topcover plate projected through the webs of said center sills andconnected with said wings, said plate depending below the top plane ofsaid wings and abutting spaced walls of said pockets.

i. In a body bolster, a unitary casting comprising a center fillerportion having vertical walls. and spaced wings. extending to aplanehigher than the top of said filler with sill pockets intermediate saidfiller portion and said wings, built up'center sills comprising verticalweb plates and having flanges resting in said pockets and a bolster topcover plate passed through openingsin the webs of said center sills, a mddle portion of said cover plate extending in alinement with bodyportions of said wings, and said cover plate being secured directly tosaid wings.

5. In a body bolster, a unitary cast ng comprising a center fillerportion having vertical walls and spaced wings with sill pocketsintermediate said filler portion and said wings, the wings extending toplane higher than the filler portion, built up center sills comprisingvertical web plates with bottom flanges resting in said pockets and abolster top cover plate passed through openings in the webs of saidcenter sills, said top cover plate lapping and. being secured to saidwings and having a. depending middle portion forming shoulders thereonadapted to contact with upper inner faces of said wings in the normalplane of said wings.

6. In a body bolster, a unitary casting comprising a center fillerportion having vertical walls and spaced. wings extending to a higherplane than said filler portion, there being sill pockets intermediatesaid filler portion and said wings, center sills comprising vertical webplates and flanges resting in said pockets and a bolster top cover platepassed through openings in the webs of said center *sills, said topcover plate having end portions lapping and be ing secured to said wingsand having an intermediate portion depending to a plane below the bodyportion of said plate, thereby forming shoulders to contact with some ofthe walls ofsaid pockets.

In witness whereof I have hereunto set my hand in the presence of twowitnesses. JACOB H. WEISBROD. Witnesses:
